    sys/dev/sym          sym_hipd.c 
  MFC: 1.69
  - Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9)
    in order to get rid of bus space handle and tag in struct sym_hcb.
  - Remove unused members related to bus addresses in struct sym_hcb.
  - sym(4) takes care of allocating an instance of struct sym_hcb
    itself so don't let newbus allocate it as an unused softc also.
  - Add basic MPSAFE locking. This includes changing the sym(4) CCBs
    to be allocated up-front instead of on demand as needed. Besides
    making these allocations more likely to succeed, this also solves
    the problem of calling bus_dmamap_create(9) with the SIM mutex
